Understanding Common Home Plumbing Upgrades

Popular Plumbing Upgrade Projects

Each project comes with its own set of requirements and challenges. Some, like faucet swaps or replacing a toilet, are manageable for handy homeowners. Others, such as repiping or relocating plumbing lines, require more expertise, specialized tools, and adherence to code.

Why Upgrade? Key Benefits

Permitting and Compliance: What You Need to Know

When Is a Permit Required?

  • Adding or relocating plumbing lines
  • Installing new bathrooms, kitchens, or laundry rooms
  • Replacing water heaters (especially gas models)
  • Major repiping projects

Minor repairs—like swapping faucets or clearing clogs—usually don’t require permits. When in doubt, call your local building department.

How to Obtain a Plumbing Permit

  1. Contact your city or county building office.
  2. Submit detailed project plans and specifications.
  3. Pay the required permit fee.
  4. Schedule required inspections (rough-in and final).
  5. Keep all documentation for insurance and resale purposes.

Skipping permits can result in fines, insurance issues, and headaches when selling your home.

Meeting Code Requirements

  • Follow local plumbing codes for pipe type, diameter, and installation methods.
  • Ensure proper venting and drainage slopes.
  • Install accessible shut-off valves on all new fixtures.
  • Use approved backflow prevention devices where required.

Most codes are based on the International Plumbing Code (IPC) or Uniform Plumbing Code (UPC), but always check your local rules for specifics.

Essential Tools and Equipment for Home Plumbing Upgrades

Basic Plumbing Tool Kit

  • Adjustable wrenches (6″ and 10″)
  • Channel-lock pliers
  • Pipe wrench
  • Hacksaw or tubing cutter
  • Plumber’s tape (Teflon tape)
  • Pipe dope (thread sealant)
  • Basin wrench (for sink installations)
  • Plunger & auger (for clogs)
  • Bucket, rags, and sponges

Specialty Tools for Advanced Projects

  • PEX crimp or expansion tool (for PEX installations)
  • Propane torch (for sweating copper pipes)
  • Pipe bender and reamer
  • Pressure gauge
  • Inspection camera (for inside pipe checks)
  • Hole saws (for wall/floor penetrations)

Rent specialty tools if you don’t plan to use them often—tool libraries or home improvement stores can help keep costs down.

DIY vs. Professional: Making the Right Call

When to DIY

  • Replacing faucets, showerheads, or toilets
  • Installing new supply lines to existing fixtures
  • Unclogging drains with basic tools
  • Swapping out washers or cartridges in valves

These jobs require patience and attention to detail, but don’t usually involve altering the home’s main plumbing layout or require permits.

When to Hire a Pro

  • Moving or adding plumbing lines
  • Major fixture relocation (e.g., moving a toilet or shower)
  • Installing or replacing water heaters
  • Whole-house repiping
  • Projects requiring code compliance and inspections
  • Dealing with gas lines or complex venting

Professional plumbers have the expertise, tools, and liability insurance to handle complex projects and ensure everything passes inspection.

Evaluating Your Skills and Comfort Level

  • Are you comfortable working under sinks or in tight spaces?
  • Do you understand basic plumbing diagrams and principles?
  • Are you able to shut off water and safely test for leaks?
  • Do you know when to stop and call for help?

If you answer “no” to several of these, it’s worth consulting a pro, at least for initial guidance.

Step-By-Step: Upgrading a Bathroom Faucet (DIY Example)

Tools and Materials Needed

  • New faucet and supply lines
  • Basin wrench
  • Adjustable wrench
  • Plumber’s tape
  • Towel or bucket

Installation Steps

  1. Shut off water supply valves under the sink.
  2. Place a towel or bucket to catch any residual water.
  3. Disconnect supply lines from the old faucet using the adjustable wrench.
  4. Remove the old faucet with a basin wrench (reach behind the sink if needed).
  5. Clean the sink surface and remove old sealant.
  6. Install the new faucet according to manufacturer instructions.
  7. Connect new supply lines, using plumber’s tape on threaded connections.
  8. Turn water back on and check for leaks.

This manageable project delivers a big style and function upgrade with minimal cost and risk.

Plumbing Upgrade Safety Checklist

  • Always shut off water (and, if applicable, power/gas) before starting.
  • Wear gloves and eye protection.
  • Use GFCI outlets for power tools in wet areas.
  • Test old pipes for lead or asbestos before cutting.
  • Ensure proper ventilation when using chemicals or soldering.
  • Keep a fire extinguisher nearby when soldering copper pipes.
  • Double-check all connections for leaks before closing up walls or floors.
  • Know the location of your main water shut-off valve in case of emergencies.

Maintenance Tips to Extend the Life of Your Upgrades

  • Inspect under sinks and around toilets monthly for signs of leaks.
  • Flush your water heater annually to remove sediment.
  • Replace washer and supply hoses every 5 years.
  • Test shut-off valves twice a year.
  • Use enzyme-based drain cleaners to prevent clogs (avoid harsh chemicals).
  • Insulate exposed pipes to prevent freezing in winter.

Consistent, simple maintenance helps avoid costly repairs and keeps your new plumbing performing at its best.
